摘要
Abstract
50mm 3C-SiC epilayers are grown on (100) and (111) Si substrates in a newly developed horizontal low-pressure hot-wall CVD reactor under different growth pressures and flow rates of H2 carrier gas.The structure,electrical properties,and thickness uniformity of the 3C-SiC epilayers are investigated by X-ray diffraction (XRD),sheet resistance measurement,and spectroscopic ellipsometry.XRD patterns show that the 3C-SiC films have excellent crystallinity.The narrowest full widths at half maximum of the SiC(200) and (111) peaks are 0.41° and 0.21°,respectively.The best electrical uniformity of the 50mm 3C-SiC films obtained by sheet resistance measurement is 2.15%.A σ/mean value of ±5.7% in thickness uniformity is obtained.关键词
